摘　　要：[目的]研究混合培养是否能够促进藻类更好地吸收二氧化碳,从而在养殖区域中降低海洋二氧化碳浓度。[方法]在舟山东极养殖区现场进行一场模拟围隔试验,将贻贝和龙须菜按照不同的比例进行培养,用于吸收海水中的二氧化碳。[结果]贝藻混合培养下对二氧化碳的去除效果优于贝藻单独培养时的去除效果。而当贝藻按照比例为1.00∶0.15以及1.00∶0.30混合下培养时,海水中的最终二氧化碳浓度分别为1.00∶0.45比例下的5.5倍和2.2倍。[结论]选择1.00∶0.45比例培养贝藻有助于对海水中二氧化碳的吸收。[Objective] The research aimed to study whether polyculture was able to promote algae to absorb CO 2 much better, thereby reducing the CO 2 concentration in the cultured area.[Method]A simulated enclosure experiment was performed in an aquaculture zone located at Dongji Island of Zhoushan. Mytilus coruscus and Gracilaria lemaneiformis were cultured in different proportions for the determination of CO 2 in seawater.[Result]The removal effect of CO 2 in algae-shellfish polyculture was better than that in monoculture. When the Mytilus coruscus and Gracilaria lemaneiformis were cultured in a ratio of 1.00 ∶0.15 and 1.00 ∶0.30, the final CO 2 concentration in seawater was 5.5 times and 2.2 times, respectively, at a ratio of 1.00 ∶0.45.[Conclusion]It will help to absorb CO 2 in seawater by selecting the proportion of 1.00 ∶0.45 in an algae-shellfish polyculture.
